Quality Control

Our Trimethoxyarsane is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profiling via advanced techniques like GC and NMR. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to relevant industry standards for high-purity electronic and laboratory chemicals to meet our global clients' exacting requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizers. Due to its volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent degradation and maintain purity.
